WITNESS INVENTOH.

The standards 1, 2 are spaced apart to receive the members 7, 8, 9, 10, and the members 9, 10 are held in spaced relation with respect to eachother to form a space 14 in which pis mounted 'the saw 15.

Each of the end sections is semi-circular in contour and consists of two curved members 46, 47; the former is an outwardly extending flange 48, the latter an inwardly eX- tending flange 49.

The outer faceof the member 4G above the flange 48, andthe inner face of the mem? ber 47 above the flange 49, .are provided-f with vertically disposed teeth 50 forming, when the end sections areconne'cted to the side sections, a continuation of the teeth 13;

The end`seetions are mounted in slidable supporting brackets 51 therefor.

4The members 47 and 50 are spaced apart, and the space between said members-forms a continuation of the space between Imembers Sand lO--of the said sections.`V The spaceV between members referred-to receive the saw 15 and the members9, 10, as well las the members 46, 47, act as clamps to hold the saw 15 in positionfto be acted upon by the saw device or the sharpening device. The brackets 51 not only act as supports for the members 46, 47, butalsol as .a1-,clamp therefor.

The end members of the combined track l and holder element are detaehably connected able and is manually propelled around thev to the side members by vdowels 52. The sections of each of the side members are detachably connected togetherfbydowels 52. Bythis arrangement the sections, `which form the track and vholder element can be conveniently removed and replaced Vwhen desired. 1

The tooth setting device, which is porttrack to set the teeth of thefsaw, consists of a bodyportion -rectangularin contour and formed of two sections16, 17, the latter having its horizontal arms 18 provided with pockets 19, into which are adj ustably mounted the'horizontal arms 20 of the section 16. The arms 20 are adjustably connected in the 'arms 18 'by set-screws 2l,v and by this arrangement the width of the body portion can be adjusted when desired. Each of the Vsections 16, 17, is provided with a pair of bosses 22 and-through which extends a shaft 23, carryinga nut 24, bearing on a boss`22, to maintain `the shaft from downward `movement. The shafts 23 are iXedin the sections 16, 17, and depend therebelow. Loosely mounted on eachof said shafts 23, isa pinion 25, which meshes with the teeth 13. The pinions 25 are arranged inpairs, and one is provided with a beveled and toothed saw set which is of greater diameter than the -pinion and isindicated at 26. The-other pinion is formed with a disk 27, having a 4straight and a beveled edge.` The disk 27 arrangement is the disk 27. These latter act 1n a manner as an anvil. i

is of greater diameter than its respective pinion and overlaps the top of the teeth 13. rlhe saw set overlaps the top of the teeth 13. The vsaw sets j26, are what may be termed tooth setting disks, and Vareoppos'itely disposed with respect to cach other and like provided with respect to l/Vhen the saw setting device is in operative position, -a toot-hed setting disk is arranged in advance of an anvil disk on one side of the track, and on the other side thereof an anvil disk is arranged in advance of the other tooth setting disk.

The pinions are maintained in position on the shafts 23 by nuts 2 The arrangementv of the disks 27 is such that each tooth, whereby one disk 27 will act on one tooth in one direction, the Vother disk will set the adjacent tooth in the opposite 'direction.

The saw sharpening device, Figs. 1, 2, 4, to 8 and 10, consists of a pair 4of brackets secured within and projecting aboveV the oval Vshaped track 'on which runs the s aw setting device. Each of Vsaid brackets is formed of a lower section 28 and an upper section 29. The-latter is hinged to the former as at 30, whereby the section- 28 can be adjusted at an angle to the section 29 and maintained in the position to which it has been adjusted. Mounted on the section 29 is an ladjustable head 31, formed with a pair of polygonalshaped openings 32 and .a socket 33 4into which extendsthe section 29. Extending through the head 3l and engaging inthe section 29 is a threaded bolt 34, andsurrounding said boltV 34 and arranged in the socket 33,E againstthe section 29,*is a coiled lspring 35.'v Carried by the threaded upper end of the bolt 34 is a wing nut 3 6'which when adjusted the position of the head 31.

Extending through the openings 32 is a pair of longitudinally adjustable rods 37, to the innerends of'which is'secured a channel shaped carrier 38.` Slidably mounted in the carriers '38 is a rectangular frame 39 having the inner face of each side bar thereof provided 'with a toothed rack40, which constitutes a series of opposed seats for a sharpening` elementlin the form of a le 41. v

When the teeth of the saw are to be sharpcned the section 29 is'swung'on itspivot to iihposition :shown in Fig. 4, and is 4then locked in such position. The framef39 `is will regulate disk will act on every alternate then sol arranged that it can be moved'hori'- 39 to be shifted longitudinally ,so that'the i file can act on successive teeth of the saw.

to a position in the path of the file carried by the frame The ends of the file are reduced so that they Will be readily positioned in the seats formed by the gullets between the teeth. The depth of the gullets is sufficient, in connection With the side bars of the frame, to maintain the file in the desired position to act on the teeth of the saw. In some instances it may be required to tilt or incline the 'file slightly; if so, an L-shaped member 42 is employed and which is notched as at 43 to takeover an end of the file. See Figs.

and 3 is such that 7 and 8. The member 42 may be detachably connected to the frame 39 or held in position by the operator.

Referring to Figs. 12 and 13 a straight track 44 is provided for the saw set 45, and in this connection the latter consists of two pinions one toothed setting disk and one beveled disk. When the saw set isrun in one direction it sets every alternate tooth. It is then reversed and run in the opposite direction and sets the other teeth of the saw. Y

The tooth setting disks used may have their peripheries set up, in a manner to provide for different shape and size saw teeth. In Fig. 3 the tooth setting disk has its periphery of a dierent shape from the tooth setting disk shown in Fig. 12. Y

The pinions traveling against the toothed racks of the members 9 and 10 tend to assist in clamping the saw in position.

The arrangement of the saw setin Figs. 1 the tooth setting disk in copies o! this patent may lie obtained for advance Will set a series of alternate teeth prior to the action of the tooth setting disk arranged at the rear of the saw set.

As the head 31 is adjustable the frame 39 can be positioned in such a manner so that the file 41 Will properly Contact with the teeth of the saw to sharpen them.

vThe pinions-25 can be removed when desired, especially when a change of tooth setting disks is required.

What I claim is 1. A machine for the purpose set forth comprising means to provide a combined track and sav:7 holder, and a portable saw set traveling against said track and including rotatable disks adaptedto act upon the teeth of a saw supported by the holder, one of said disks having a toothed periphery and the other a beveled periphery.

2. A machine for the purpose set forth comprising means to provide an extensible and eontractible combined track and saw holder, and a portable saw set traveling against said track and including rotatable Y disks adapted to act upon the teeth of a saw supported by the holder, one of said disks havingv a toothed and the other a beveled periphery.

3. A machine for the purpose set forth comprising means to provide a combined track and saw holder, anda portable savv set comprising a front and a rear pair of rotatable disks capable of acting on the teeth of a saW supported by said holder, one of the disks of each pair having a toothed periphery and the other disk of the pair having a beveled periphery.
